    Crashed 18 4runner ECU ... TWICE

    Any one had issues with flashing the 4runner ECU ? Had it go through the initial pace , where to key off , wait 10 sec , and key on . Then it says cntl : Failed to Intl.
    First ECU was blanked out . Could not read or connect with dealer tools.
    Got a second ECU , and re did VIN .. started Tuning and after 8 successful writes ... same thing. Bricked.
    Any ideas from others as to why this is happening ? Done may toyotas before , and never had this much trouble .
    Strong Internet Connection , undid battery terminal as per request.
    Dialing in a TRD Pro wth 1050 ID Injectors and Whipple Supercharger.

    I didnt even think the 2018 4runner was supported. Ive been trying to tune my wifes 2020 for months with no support. Cant even find a stock bin file to edit with WinOLS. Care to share the stock file?
